I just sold a preamp and the buyer is claiming that it is DOA. I know for a fact that it was good when I sent it. I used it for a gig the week prior to shipping and to test a speaker cab a few days prior to shipping. The seller replaced the fuse and that solved the problem - only for a awhile!! The fuse continues to blow. Something is shorted in the preamp (Kern) that is causing the fuse to blow. The seller sent me an email and asked for a refund. I kind of refused because I can not say for certain he isn't responsable for breaking it or that it wasn't damaged during shipping. I sent him an email back asking him to get an estimate and that we would go from there. He replied and asked me to paypal him $38 bucks to cover the cost of an estimate. I sent him $20 and told him I would cover half of the cost. Since then, he refunded my $20 from paypal from paypal for the estimate. I think this one might get ugly. What should I do?? I know this thing worked before I shipped it - thats a fact! I am against refunding him the money because I dont know how it got broke and we never really discussed returns when when the deal was being made. Did this guy break it and is now trying to pull one over on me or am I being an a**hole by not giving his money back? I am willing to see the guy halfway on just about everything but I dont want to get screwed - nor do I want him to get screwed. I shipped the Kern via Fedex and it was packaged well. Should I start a claim with Fedex? This is the first time this has ever happened to me. Your guidence would be appreaciated.
